This tech demo scene demonstrates how to simulate and interactively cut strings using Blender's built-in physics and modifier systems. The setup relies on a precise modifier stack order, utilizing the cloth modifier for the base physics simulation. Dynamic paint and vertex weight mix modifiers are combined to dynamically edit weight maps, enabling the cutting effect.
Additional volume is generated using displace and solidify modifiers. The scene also includes a specialized setup using an invisible object and the surface deform modifier to drive the string simulation during the uncut phase. Users are encouraged to study the vertex groups and modifier stack to understand the workflow.
